Ingredients
For the meatballs
2 lb (900 g) ground beef, preferably 80–85% lean
1 large egg
½ cup (50–60 g) plain breadcrumbs
¼ cup (25 g) grated Parmesan cheese, optional
2 cloves garlic, minced
1 teaspoon onion powder
1 teaspoon dried parsley
½ teaspoon ground black pepper
½ teaspoon salt, or to taste
For the potatoes and French onion gravy
2 lb (900 g) baby potatoes, red or yellow
1 can (10.5 oz / 298 g) condensed French onion soup
1 cup (240 ml) beef broth
1 tablespoon Worcestershire sauce
1 teaspoon dried thyme
½ teaspoon black pepper
1 tablespoon olive oil, optional for browning the meatballs
1 tablespoon cornstarch
2 tablespoons cold water
1 tablespoon chopped fresh parsley, for garnish
Optional additions
1 medium yellow onion, thinly sliced
1 teaspoon garlic powder for extra flavor
½ cup (50–60 g) shredded mozzarella or provolone cheese
2–4 tablespoons sour cream for a creamier gravy
Equipment needed
5–7 quart (4.7–6.6 litre) slow cooker
Large mixing bowl
Measuring cups and spoons
Whisk or fork
Large skillet, if browning the meatballs
Meat thermometer, for checking doneness
Instructions
Step 1: Prepare the potatoes
Wash the baby potatoes thoroughly under running water.
Leave small potatoes whole and cut larger potatoes in half so they cook evenly.
Arrange the potatoes in an even layer across the bottom of the slow cooker.
Sprinkle with the thyme and black pepper.
If using sliced onion, spread it over the potatoes.
Tip: Cut potatoes into similar-sized pieces to ensure they become tender at approximately the same time.
Step 2: Make the homemade meatballs
Place the ground beef in a large mixing bowl.
Add the egg, breadcrumbs, Parmesan cheese, minced garlic, onion powder, dried parsley, salt, and black pepper.
Mix gently with clean hands or a fork until the ingredients are just combined. Avoid overmixing, which can make the meatballs dense.
Shape the mixture into approximately 20–24 meatballs, each about 1½ inches (3.5–4 cm) wide.
Place the meatballs on a clean plate while you prepare the sauce.
Tip: If the mixture feels too wet, add 1 tablespoon of breadcrumbs at a time. If it feels dry, add 1 tablespoon of water.
Step 3: Brown the meatballs (optional)
Heat the olive oil in a large skillet over medium-high heat.
Add the meatballs in batches, leaving space between them.
Brown them for approximately 2–3 minutes per side, turning gently.
Transfer the browned meatballs to a plate.
The meatballs do not need to be fully cooked at this stage. Browning adds flavor and helps the meatballs hold their shape, but you can skip this step to save time.
Step 4: Prepare the French onion gravy
Open the can of condensed French onion soup.
Add the soup to a bowl with the beef broth and Worcestershire sauce.
Whisk until the mixture is reasonably smooth.
Taste the mixture before adding any additional salt, since canned soup and broth can already contain substantial sodium.
Important: Use condensed soup as directed in this recipe; do not prepare it with the amount of water specified on the can. The beef broth provides the liquid needed for the slow cooker.
Step 5: Assemble everything in the slow cooker
Pour approximately half of the French onion mixture over the potatoes.
Arrange the meatballs in a single layer on top of the potatoes, or in a slightly overlapping layer if necessary.
Pour the remaining gravy mixture evenly over the meatballs.
Cover the slow cooker with its lid.
The potatoes should sit mostly beneath the meatballs, allowing them to absorb the flavorful onion gravy as they cook.
Step 6: Slow cook
Choose one cooking setting:
LOW: 5–6 hours.
HIGH: 3–4 hours.
Cooking time varies with the size of the potatoes, the size of the meatballs, and your slow cooker.
Keep the lid closed as much as possible to maintain the cooking temperature. Begin checking the potatoes toward the earlier end of the cooking window.
The dish is ready when:
The potatoes are fork-tender.
The meatballs are cooked through.
Ground beef meatballs reach an internal temperature of 160°F (71°C), measured in the center with a food thermometer.
Do not rely on color alone to determine whether ground beef is safely cooked.
Step 7: Thicken the gravy
If the gravy is thinner than you prefer:
Mix 1 tablespoon of cornstarch with 2 tablespoons of cold water in a small bowl.
Stir until no lumps remain.
Gently stir the slurry into the cooking liquid, avoiding breaking up the meatballs.
Cover and cook on HIGH for another 15–20 minutes, or until the gravy thickens.
If you prefer a thinner, more broth-like sauce, you can omit the cornstarch.
Step 8: Add optional cheese or cream
For a cheesy finish, sprinkle shredded mozzarella or provolone over the meatballs during the final 10 minutes of cooking. Cover until melted.
For a creamier gravy, switch off the slow cooker and stir in 2–4 tablespoons of sour cream. Avoid boiling the sauce after adding sour cream, as it may separate.
Step 9: Garnish and serve
Taste the gravy and adjust the pepper or salt if necessary.
Sprinkle with fresh parsley.
Serve the meatballs and potatoes with plenty of French onion gravy spooned over the top.
Enjoy immediately while hot.

Actual nutrition will depend on the ground beef’s fat content, the brand of soup and broth, portion size, and any optional ingredients. Sodium can be particularly high in condensed soup and commercial broth.
Nut information and allergy details
Peanuts: None intentionally included.
Tree nuts: None intentionally included.
Nut-free preparation: Check the labels on the French onion soup, breadcrumbs, Worcestershire sauce, broth, and seasonings for allergen declarations and cross-contact warnings. If preparing food for someone with a serious nut allergy, use products verified as safe for that person’s allergy requirements.
Other potential allergens: Egg in the meatballs, wheat or gluten in ordinary breadcrumbs and some sauces, and milk in Parmesan, mozzarella, provolone, or sour cream.
Dairy-free variation: Omit Parmesan, cheese, and sour cream, and verify that the packaged ingredients are dairy-free.
Gluten-free variation: Use certified gluten-free breadcrumbs, gluten-free Worcestershire sauce, and soup and broth verified to be gluten-free.
Nuts are not needed as a garnish or ingredient in this recipe.
Storage and reheating
Refrigeration: Allow leftovers to stop steaming, then refrigerate in shallow, airtight containers within two hours of cooking. Store for up to 3–4 days.
Freezing: Freeze the cooked meatballs and gravy in airtight freezer-safe containers for approximately 2–3 months for best quality. Potatoes may become softer or grainier after freezing.
Reheating: Reheat on the stovetop over medium-low heat or in the microwave until the center reaches 165°F (74°C). Add a splash of beef broth or water if the gravy has thickened too much.
Thaw frozen leftovers in the refrigerator rather than on the counter.
Troubleshooting
The potatoes are still hard. Continue cooking and check again in 30-minute intervals. Large whole potatoes may need more time.
The gravy is too thin. Add the cornstarch slurry and cook for another 15–20 minutes on HIGH.
The gravy is too salty. Use low-sodium broth next time, avoid extra salt in the meatballs, and dilute the finished gravy with a little unsalted broth or water.
The meatballs are falling apart. Mix the meatball ingredients gently, use enough breadcrumbs and egg, and brown the meatballs before adding them if possible.
The meatballs are dry. Use ground beef with some fat, avoid overmixing, and check doneness with a thermometer rather than extending the cooking time unnecessarily.
The potatoes are mushy. Cut them into larger pieces, use waxy baby potatoes, and check the dish earlier during cooking.
Best serving suggestions
This dish is filling on its own, but it also pairs well with:
Steamed green beans or broccoli.
A fresh green salad with vinaigrette.
Roasted carrots.
Crusty bread to soak up the gravy.
Steamed peas or sautéed cabbage.
Final recommendation: For the closest result to the dish in your photo, use homemade beef meatballs, halved baby potatoes, one can of condensed French onion soup, and beef broth. Cook on LOW for about 5–6 hours, then thicken the gravy if needed. This gives you tender potatoes, flavorful meatballs, and rich onion gravy without requiring constant attention.
